For the Ultimate, Sram held nothing back. Our engineers sculpted the finest materials – titanium and carbon fiber – to make this our lightest four-piston brake ever. Power, modulation and lever feel set a new standard. Personalization is quick and intuitive. And for performance – well, Srams test riders didn’t dub it the “Mini-Code” for nothing.

Bleeding Edge
Bleeding Edge technology allows quick and easy bleeding of the brakes. The new fluid channel and redesigned bleed port make it easier to pump fluid through the caliper. A special adapter can be placed on the vent and seals the system to prevent air ingress and fluid loss.

Pressure point adjustment
Some people like the immediate power transmission of a short lever stroke. Others prefer the feeling of a longer lever stroke. With the pressure point setting you can determine the position where your fingers are supposed to be, into the brakes are applied. This allows you to quickly and easily adjust the feel of your brakes to your needs without having to move the brake pads. In addition, both brake levers can be adjusted to feel exactly the same.

Lever Pivot Bearings
Sealed precision bearings on the rotary handle provide a clean, precise grip movement and allow smooth one-finger operation.

Power Reserve Geometry
Basically, a brake lever only increases the force generated by your hand (just like a nutcracker). SRAM’s Power Reserve Geometry offers a way to combine great leverage with great comfort for your hands. This philosophy is fundamentally different from other brake manufacturers. Due to the position of the fulcrum and physical laws, other brake levers tend to make your fingers slip from the ends of the levers as you pull. SRAM brakes are different. With our brake levers, the fulcrum of the grip is closer to the handlebar – closer than any other brake on the market. The resulting lever movement doesn’t move inwards so much, creating an arc more like the natural movement of your fingers. This transfers more force to the brake. And the great thing is: Every¬†SRAM lever offers this function.

When you pull a new SRAM brake lever, you notice the difference immediately. A shorter empty path. An optimized actuation of the brake pads. The new cam design requires a shorter lever travel to push the brake pads in the direction of the brake disc. That’s nice, but for perfect braking performance you need more than just power. You need control. Many brake systems offer a shorter empty travel – but at the expense of modulation. SwingLink solves this problem with its special cam shape. When the brake pads touch the brake disc, the force is modulated and the “stagnant” braking sensation is avoided. This creates the perfect balance between power and precision.

Timing Port Closure
The synchronization opening of a hydraulic brake is the connection between the reservoir and the main cylinder bore. When the lever is actuated, a cup collar passes through this area and closes the opening, pressurizing the system. SRAM’s new TPC Plus synchronizing port closure system features durable seals and an ultra-soft cylinder bore surface for reliable and consistent braking performance.

S4 Light-Weight 4-Piston Caliper

The all new S4 Caliper features four Machined and Moly-coated aluminum pistons for consistent rollback and easy set-up, Heat shield insulation and Bleeding Edge porting and adapter technology for easy bleeds.
